mov metal oxide varistor

TGE Mov varistor is a non-linear voltage characteristics of the resistance of the device is mainly used in the voltage clamp circuit withstand over-voltage, absorbing excess current to protect sensitive devices. English name called "Voltage Dependent Resistor" abbreviated as "VDR", or called  mov varistor. Varistor resistive material is a semiconductor, so it is a variety of semiconductor resistor. "Zinc oxide" Now a lot of use of (ZnO) varistor metal oxide, its main material divalent element zinc (Zn) and hexavalent elemental oxygen (O) of the composition. So from the point of view of materials, the zinc oxide  High voltage varistor is a "Ⅱ-Ⅵ family-oxide semiconductor." In China Taiwan, varistors called "surge absorber", sometimes also referred to as "electric shocks (surge) suppressor (absorber)."
